To all u'lwmit may concern:

Be it known that 1, JOHN L. Cur-:vnuxo, a resident of New York. in thecounty and State of New York have invented certain new and usefulImprovements in Electric Regulation, as set forth in the annexeclspecitication' and drawing; forming a part thereof,

My invention pertains to that class of electric regulation wherein it isdesired to auto A further.objectofinyinvention isto prw vitle means forautomatically lfegtll tllllllg'tllt voltage impressedupon.t'ranslatjing' devices; the current consumption of which is subjectto wide variations.

As myinventiou is particularly'applicable to a syste'ni \vhereinagenerator; is nscil for charging storage battery and operating lamps orother translatingdevices in connection therewith, it will be describedwith reference to such-a system.

The drawing is a diagrammatic representation of one forrnof such asystemin which the elements of my in ention are embodied.

In the drawin generator the positive brush of which is con nected as bylead 'with one side of the storage battery 3, and oneside of the gron'is of lamps or othi. translatin devices iiulicatccl at i, :3, ano (3rcspcctivelv The other sides of the groups oftranslating' devices areled to the inainsT, and 9 .r spectively: which lead to contacts 10, Itand i2 rcspec- Li ely, of a seritof switches having contact knives ormembers 13. H and 15. adapted n'pon closing of the switches. to connectthe said mains with the contacting members 1?. 18 ancl 19 respectively.The said knives or contact members 13, ll and 15 are all clectricallyconnected together as h means ol the \virelti, so that, for example.when the member 13 is so swung as to elcctricallv connect i0 and 17. thewire 16 will be in elcctricpgeonnection with the wires and '20 for apurpose, which will hereinafter more plainly a'ipear. The contacts 1?.l3 and 19 are connected as by wires 20, '21 and 22 to'the .negative poleof the batter-v (represents a dynamo or variable resistances 23.

"The other culls of the r'illtl carbon pilcsare electrically connected together as b means of thevoke 26 from whichthe lead 2? is carried to the the switch 23 to the negative pole of thegen. erator l.

V The solcnoiilj-IB is iconneclnl with the lead 1 as bv uieans-of-tlieThe practical operation ofvnrv invention is substantially as follows:-If the generator lurnnning and having: a voltage in,excess of.

the storage battery ambthe switch "25 be closed. current will llow fromthe generator" Y through lQiHl L. battery 3. lead 3?. switch '25 tothe'gcin-rator. which current will serve to charge the battery. It now.it be 'ilcsircvl to throw on the translating \l'eviccs lllllli tltt llby the group 4. the sivitcbfll-lnia v 'beclcseil and current \\'lll thenflow through the generator from learl '2. translating devices i,

the resistance of" the pile 23 and thus tend to lower the voltage acrossthe translating devices 4. I so adjust the spring 33, that when the.normal voltage across the translating devices 4 is reached, anyappreciable crease above this amount, will cause the lever 32- to bedepressed and the resistance 23 to be increased in such iii ier;asto'liold the voltage'coiistantf{The c it"now 'tlievoltage across thegenerator shall. rise, as for example, when the batteries becomecharged, the voltage across the translating devices l will tend to riseand the current in coil 35 will tend to rise and thus cause theresistance 23 to be increased in such manner as to hold the voltage ofthe translating devices r substantially constant. It now, it he desiredto throw on the trai'islating devices indicated at 5, theswitchineiiiber H may he closed across thecoi'itacts 11 and 18 and thencurrent will flow from the lead Qthrough trans 'lating devices 5,mainbf, contact 11, switch member 14, contact 18, wire 21, carbon pile Al. to lead 27. As the load indicated at 5 is thrown oiras abovedescribed, it will be noted that the carbon pile 24 is siinultance"ously thrown into circuit in shunt with the carbon pile 23 iii-suchmanner as tOlIlClZCflSt'.

the carrying capacity of the resistance varying device governed by" coil-35; as tlieload if it be desired to throw on the translating devicesindicated at (3, the switch member 1511121),btLtlllOWll so as to causeconnection between 12 and 19 and then current will ll w from th'e lead2, through the translatingdevices (3, main 9, contact 12, member 15,contact 10, wire 22, resistance 25, lead 27 and, with the threetranslating circuits now thrown on across the leads, there are alsothreecarbon piles all in multiple to carry the load.

It will be obvious that the various groups of: translating deviccs' willall be'subjcctcil to the same voltage as tlie mains 7, S and 9 will bein electrical connection with each other through the wire 16 when theirre spective switches are closed, and the coil 35 will be subjected toany changes in voltage across the translation circuits, regardless ofwhich switches a re closed, owing to the con vlicctioii of wire 16 withall the circuits in operation and it will he plain from the abovedescription of the ell'ect of the current and coil 35, that the samewill tend to hold the voltage upon allthc translation circuits. con- Istant through variations in the supply cir cuit. I

It will be obvious that as many groups of translating devices, shown asthree in iuuiiher in the drawing. may be employed as desired and that asch froup is thrown into circuit across the "dials, the capacity of theautomatic resistance regulating means will be accordingly increased. Itwill also he noted that as any of the circuits containing circuit as.the circuits are cutout. Iii-this manner I provide an a'ntoinaticresistance voltage regulating meahs capable of increasing the drop in acircuit through a wide range] and also capable of carrying heavycurrents with little drop when desired.

It will be obvious that any number of re-" sisters inay he used and thatany type of resist-0r suitable for the. purpose may be ein ployed; alsothat any i 'ieansmay be employed for automatically operating the re-'sistance varying n'ieans,'whirh in this iiistance I have indicate(l asoperated by the solenoid 35 for the sake of simplicity. the same being awell-known construction used in this type of systems.

I do not wish in any way to limit myself to the exact construction ordetails set forth in the accoin'pan \-'ing drawing which is :1
